Abstract
Die Bundesregierung strebt bis zum Jahr 2010 eine Verdopplung des Anteils erneuerbarer Energien am Primärenergie- sowie am Bruttostromverbrauch an. Das vorrangige Ziel der damit verbundenen Umstrukturierung des Energiesektors ist die Verbesserung der Umweltqualität. Es darf jedoch nicht außer Acht gelassen werden, dass die Förderung erneuerbarer Energien zwangsläufig auch gesamtwirtschaftliche Auswirkungen hat. Angesichts der anhaltend angespannten Lage am Arbeitsmarkt stehen dabei insbesondere die Beschäftigungseffekte der Förderung erneuerbarer Energien im Mittelpunkt des öffentlichen und wirtschaftspolitischen Interesses. Vor diesem Hintergrund hat das Institut für Wirtschaftsforschung Halle im Auftrag des Bundesministeriums für Wirtschaft und Arbeit (BMWA) die gesamtwirtschaftlichen und insbesondere beschäftigungsrelevanten Auswirkungen des angestrebten Ausbaus erneuerbarer Energien untersucht. Im Gegensatz zu anderen Studien dieser Art wurde dabei besonderer Wert auf eine dynamische Analyse gelegt, die neben den expansiven Beschäftigungsimpulsen im Bereich der erneuerbaren Energien auch die gegenläufigen Beschäftigungswirkungen berücksichtigt, die durch Verdrängung konventioneller Energieträger und durch erhöhte Steuern zur Finanzierung von Subventionen für regenerative Energien entstehen. Die vorliegende Untersuchung gibt eine zusammenfassende Darstellung der Vorgehensweise und der Ergebnisse des Forschungsprojekts. Es zeigt sich, dass per saldo durch den verstärkten Ausbau erneuerbarer Energien keine zusätzliche Beschäftigung generiert wird.

Promotion of investment in East Germany - Results of an empirical study of effectiveness
Harald Lehmann, Andreas Stierwald
Wirtschaft im Wandel,
No. 5,
2004
Abstract
In Germany considerable amounts of public funds are being spent on business development programs. In order to do so economic reasoning is needed. In particular the programs for supporting investment lack microeconometric empirical evaluation. To close this gap the special program „Gemeinschaftsaufgabe zur Verbesserung der regionalen Wirtschaftsstruktur“ (GA) is exemplarily analyzed. This program is intended to strengthen the capital stock of the East German economy, so firms of the East German manufacturing industries will be studied. A comparison of the two fundamental methods for microeconometric evaluation shall demonstrate the general problems in analyzing the effectiveness of development programs. The matching estimator provides more stable results then a sample selectivity model. The results suggest that the GA generates considerable extra investment activities.

Softening Competition by Inducing Switching in Credit Markets
Jan Bouckaert, Hans Degryse
Journal of Industrial Economics,
No. 1,
2004
Abstract
We show that competing banks relax overall competition by inducing borrowers to switch lenders. We illustrate our findings in a two-period model with adverse selection where banks strategically commit to disclosing borrower information. By doing this, they invite rivals to poach their first-period market. Disclosure of borrower information increases the rival's second-period profits. This dampens competition for serving the first-period market.

A model of private households´ consumption expenditure on the basis of representative income and consumption statistics

No. 16,
2004
Abstract
The accurate measurement of the level and composition of private consumption is one of the crucial tasks of official statistics. There are different ways of measurement that have to be compared and assessed. In the following, a comparison between a supplier side based and a consumers side based measurement (household budget surveys) shows, that the the later one still has some drawbacks. Additionally the household budget surveys are used for microeconometric consumption analysis. Recommendations, potentials and drawbacks will be worked out.

Diversifikation und regionale Wirtschafts- und Beschäftigungsentwicklung - Eine empirische Analyse für ausgewählte deutsche Gebiete
Peter Haug
Jahrbuch für Regionalwissenschaft,
No. 2,
2004
Abstract
This article analyses the effects of heterogeneous economic structures on the long-term development of regional employment. A simple model is introduced to illustrate the beneficial outcomes for households as well as for enterprises of locating in highly diversified municipalities because risk (volatility of income, recruitment costs in a broader sense) diminishes for both. Econometric results for a sample of municipalities in Lower Saxony provide some evidence for a positive effect of local economic diversification on employment opportunities. The results seem to be not confined to the aggregated local labour demand but also apply to most branches the local business sector.

Evolving Structural Patterns in the Enlarging European Division of Labour: Sectoral and Branch Specialisation and the Potentials for Closing the Productivity Gap
Johannes Stephan
IWH-Sonderhefte,
No. 5,
2003
Abstract
This report summarises the results generated in empirical analysis within a larger EU 5th FP RTD-project on the determinants of productivity gaps between the current EU-15 and accession states in Central East Europe. The focus of research in this part of the project is on sectoral specialisation patterns emerging as a result of intensifying integration between the current EU and a selection of six newly acceding economies, namely Estonia, Poland, the Czech and Slovak Republics, Hungary and Slovenia. The research-leading question is concerned with the role played by the respective specialisation patterns for (i) the explanation of observed productivity gaps and for (ii) the projection of future potentials of productivity growth in Central East Europe.
For the aggregated level, analysis determines the share of national productivity gaps accountable to acceding countries’ particular sectoral patterns, and their role for aggregate productivity growth: in Poland, the Slovak Republic and Hungary, sectoral shares of national productivity gaps are considerable and might evolve into a ‘barrier’ to productivity catch-up.Moreover, past productivity growth was dominated by a downward adjustment in employment rather than structural change. With the industrial sector of manufacturing having been identified as the main source of national productivity gaps and growth, the subsequent analysis focuses on the role of industrial specialisation patterns and develops an empirical model to project future productivity growth potentials. Each chapter closes with some policy conclusions.

Why do we have an interbank money market?
Jürgen Wiemers, Ulrike Neyer
IWH Discussion Papers,
No. 182,
2003
Abstract
The interbank money market plays a key role in the execution of monetary policy. Hence, it is important to know the functioning of this market and the determinants of the interbank money market rate. In this paper, we develop an interbank money market model with a heterogeneous banking sector. We show that besides for balancing daily liquidity fluctuations banks participate in the interbank market because they have different marginal costs of obtaining funds from the central bank. In the euro area, which we refer to, these cost differences occur because banks have different marginal cost of collateral which they need to hold to obtain funds from the central bank. Banks with relatively low marginal costs act as intermediaries between the central bank and banks with relatively high marginal costs. The necessary positive spread between the interbank market rate and the central bank rate is determined by transaction costs and credit risk in the interbank market, total liquidity needs of the banking sector, costs of obtaining funds from the central bank, and the distribution of the latter across banks.
